Distributed version control
- Many copies of the code all over the world
- Many people working together on the code
- Let tools help us understand and combine our code
- The less we do manually the less error prone things are
Isolate new code
- Make a copy of the primary code—called a branch
- Do changes on the new branch
- (Pull changes from the original branch into the new branch if necessary)
- Send the new coded feature to GitHub for teammate review and approval
Prevent overwrites
- With branching we can help prevent code overwrites
- GitHub will automatically merge when it can
- GitHub will announce if there is a conflict in the code
- GitHub is there to help us not hinder us
Prevent stupid mistakes
- Code reviews from teammates to find small mistakes
- It’s the original author’s job to fix the problems
- Can learn from reviewing—and being reviewed
